Medical imaging may help researchers understand the pathogenesis of H1N1 virus

Researchers used medical imaging to identify a severe case of H1N1 after a negative nasal swab test. CT scans revealed peripheral ground-glass opacities, which raised suspicion of the virus and were later confirmed as a cause of death. The study suggests that early CT scans may help clinicians recognize cases of severe influenza.
